' Specification of Letters Patent.

Patented Sept. 24, 1918.

Application filed. November 27, 1916. Serial No. 133,602.

To all whom it may concern: 1

Be it known that I, ROBERTS. LAVENDER, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Door-Fasteners; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to means for fastening doors in the openedposition.

The object of my invention is to produce a simple, cheap arid eflectivedevice for fastening doors in the opened position, which device shall becapable of being placed in an unobtrusive position and which shall notfasten the door unless it is desired to fasten the same, but which shallat all times serve as a stop for the door in the open position in orderto prevent the latter from striking and marring chair boards, walls,etc.

A further object of my invention is to provide such a fastener which canbe moved into engagement with the door and disengaged therefrom bysimple motions of the foot.

In carrying out my invention, I make use of the instrumentalitiesillustrated in the following figures; in which,

Figure 1 is a perspective view showing a portion of the floor, a chairboard, door jamb and door with my improved door fastener appliedthereto, the door being in the opened position and fastened.

. Fig. 2 is an enlarged view similar to Fig.

1, but omitting the floor, chair board and door jamb.

Fig. 3 is a plan view of a portion of a door in theopen position showingthe manner in which my improved fastener serves as a door stop.

Fig. 4 is a section of the floor and my improved door fastener along theline 44 7 in Fig. 1 and looking in the direction of the arrow 4 in saidfigure.

10 represents a floor, 11 is a chair board, 12 is a door jamb and 13 isa door, all of these parts being of the ordinary construction andforming no part of my invention. 14 represents the door fastener, whichcomprises the body portion 15 provided with a hole 16.

A screw 17 has its body portion passing loosely through the hole 16 andits threaded portion is screwed into the floor 10, as shown .in Fig. 4.

A washer 18 is placed between the head of the screw 17 and the body 15,and a second washer 19 is placed between said body portion andthe floor10.

The washer 19 is to be made of any height so that the under side of thedoor fastener 14 may clear rugs, carpets, mattings, etc., that may beupon the floor.

The door fastener also comprises a lever portion 20 which extends to oneside of the body portion 15 and terminates in a nose 21 having a curvedsurface 22 inclined to the lever portion 20 and a surface 23 at rightangles thereto. To the flat surface 23 I preferably attach a felt pad 24for a purpose hereinafter referred to.

The body portion 15 is provided with a curved surface 25 where it joinsthe lever portion 20 and I mount a rubber, felt, or other buffer 26 onsaid curved surface for a purpose hereinafter referred to.

The operation of my improved door fas tener is as follows:

The door fastener 14 being attached to the floor by the screw 17 inproximity to the chair board, as shown in Fig. 3 and being allowed torest in the position shown in full lines in said figure, the door 13 canbe opened and shut without bringing the door fastener 14 into fasteningrelation with the door 13, but during this mode of operation of myimproved fastener, the bufler 26 will serve to limit the movement of thedoor and prevent it from striking the chair board 11, consequently myimproved fastener thus operates as a door stop.

It is also evident, by reference to Fig. 3, that the corner 27 of thebody 15 will strike the chair board 11 and prevent the nose 21 frommoving further toward the left than is shown in said figure.

When it is desired to fasten the door in the open position, the nose 21is to be moved to the position shown in full lines in Figs. 1 and 2 andin dotted lines in Fig. 3. This can be done either by the hand or foot.When the nose 21 has been moved as just described, the pad 24 and thebuffer 26 will embrace the sides of the door and prevent same frommoving.

It is evident by an inspection of Fig. 3, that the corner 28 of the body15 will strike the chair board 11 when the nose 21 is moved to theposition shown dotted in said figure, consequently should the nose 21 beso moved While the door is closed and the door afterward be opened, thecorner 29 of the door Will strike the'curved surface 22 of the nose 21and move the same approximately to the position shown by full lines insaid figure, thus permitting the door 13 to strike the buffer 26Without-producing any undue stress on the nose 21.

I claim:

The combination With a floor, a door, a chair board and a screw securedin said floor, of a door fastener pivotally mounted on said screw, saiddoor fastener comprising a body portion provided With a hole for thereception of said screw, a lever portion, a nose portion provided With aflat surface for holding said door and a curved portion for moving saidnose out of the path of said door, said body portion having a curvedsurface and a buffer mounted thereon for stopping said door, said bufierbeing so located that the contact of said door therewith does not movesaid fastener to lock said door, and corners on said body portionlocated to strike said chair board and limit the movement of said doorfastener.

In testimony whereof I affix my signature.

ROBERT S. LAVENDER.
